Only 7? And the last one is Anglo-America?
What is the target audience for this 7 World Powers Tour if not JWs? Who else would ever go?
And if only JWs would go, then the business model is pretty obvious. Just give them a lot of your money, with no upper limit, and have your inaccurate philosophy of history reaffirmed for you.
Don't pay the sucker a dime and see what happens.
